Here we find that hydrogen-bonded organic frameworks can serve as photocatalysts for under above-mentioned conditions. Specifically, constructed donor–acceptor framework exhibits high photocatalytic activity photosynthesis, with production rate 681.2 μmol g-1 h-1. The control experiments theoretical calculation revealed structures not only accelerate charge separation transfer but also optimize reaction pathways, which significantly boosts photosynthesis.

Water-based electrolytes provide safe, reliable, and cost-effective energy storage solutions; however, their application in aqueous lithium-ion batteries is hindered by low density short cycling life due to the limited electrochemical stability window. While high lithium salt concentrations can mitigate some of these issues, they often lead increased solvent viscosity higher costs, limiting commercialization. In this study, a boron-stabilized anisotropic polyvinyl alcohol (PVA) hydrogel electrolyte, referred as BaP, proposed address challenges related (LiTFSI) concentrations. Due Hofmeister effect, BaP water-in-polymer electrolyte retain concentration even when are used. Briefly, promotes salting-in phenomenon Li ions, while TFSI ions induce salting-out, allowing synergistically achieve unique characteristics, exhibits wide window similar that highly concentrated electrolytes, enabling stable operation LiMn2O4||Li4Ti5O12 full cell suppressing hydrogen evolution. Moreover, biodegradability contributes development more environmentally friendly battery system.

Abstract Unsatisfying preparation controllability, mechanical properties, ionic conductivities, and working voltage windows limit the practical applications of solid polymer electrolytes (SPEs) in lithium‐metal batteries. Herein, a 3D printing strategy combined with zwitter molecule modification is proposed to efficiently solve problems SPEs polyvinylidene fluoride‐hexafluoropropylene (PH) matrix. The electron‐donating property resulting from carboxyl groups aspartate acid (Asp) induces cis‐conformation change fluoride, which enhances Li + transport anion immobilization on chains. In addition, amphoteric functional Asp simultaneously promote lithium salt dissociation desolvation N,N‐dimethylformamide, thus leading formation stable 3 N/LiF‐enriched interphases between electrodes electrolyte. Moreover, technology increases continuity uniformity SPE membrane, further increasing conductivity properties. As result, exhibits high (1.20 × 10 −4 S cm −1 ), large transfer number (0.68), wide electrochemical window (4.6 V), good tensile strength (≈110 MPa), endowing half cells cycling performance over 2000 h low overpotential 40 mV. Furthermore, high‐energy densities (492 Wh kg 1303 L ) are delivered by pouch cell SPE, indicating application prospects.

The designability of crystalline framework materials holds promise for the development stable solid-state electrolytes with high ionic conductivity. In this study, we present three anthraquinone-based hydrogen-bonded organic frameworks (iHOF-21-23), which possess 2D sandwich-shaped hydrogen-bonding networks. By modulating anthraquinone substituents, iHOFs exhibit distinct ion-transport sites. Specifically, both carbonyls in structure iHOF-22 are sites, whereas only one carbonyl each iHOF-21 and iHOF-23 is, thus exhibits higher conductivities. conductivities Li+, Na+, K+ at 30 °C 1.37 × 10-4, 1.14 9.76 10-5 S cm-1, respectively, 16-47% than those iHOF-23. design multidimensional ion transport provides valuable insights various batteries.
